IMPROVEMENT IN GAS-RETORT MQUTH-PIECES.

Specification forming part of Letters PatentNo. 144,857, dated November25, 1873; application filed October 3, 1873.

To all whom it may concern:

Be it known that I, PETER MUNZINGER, of the city and county ofPhiladelphia and State of Pennsylvania, have invented an Improved RetortMouth-Piece for Gas-Works, of which the following is a specification:

The invention consists of a retort mouthpiece having an inlet soft-metalbase for the retort-lid, and a water-chamber to protect the said basefrom the heat of the retort.

Figure l is a view of a retort in connection with a sectioned view ofthe improved mouthpiece and attachments. Fig. 2 is an end view of theimproved mouth-piece.

A is a retort, of clay or oth er m aterial, or metal. B is amouth-piece, flanged and bolted to it. Like the retort, it can be of anysuitable material or metal, and of any form. The outer end of themouth-piece B has an inlet base or ring, of lead or other soft metal, a,which is capable of resisting the deleterious action of the gas. Itconforms to the depending rim 1) of the lid 0, which should be trued andground before being set against it. A screw, D, passing through the boss0 of the cross-bar E, and pressing against the center of the lid, forcesthe depending rim perfectly gastight against the metal base. Althoughthe gas in the retort has no perceptible influence upon the softmet-albase, the heat from the retort has a decided tendency for softening andmelting it; to obviate which a Water chamber or jacket, 1*, is formed inthe enlargement around the mouth-piece, sufficiently near to thesoft-metal base to absorb and carry off the heat with the water.

I am aware that a lead base has been applied directly to the mouth of aretort; but this of itself is not sufficient, owing to the intense heat.I am also aware that a waterjacket has been used in combination with avulcanized-rubber packing. Neither of the above devices are claimed byme.

I claim as my invention-- The retort mouth-piece B, having a softmetallid-base, a, in connection with a waterjacket, F, as and for the purposeshown and described.

In testimony whereof I hereunto sign my name in presence of twosubscribing Witnesses.

PETER MUNZINGER.
